Description
Technical Field
[0001] The invention relates to the field of shaft retaining ring installation tooling, in particular to a shaft earless retaining ring continuous supply portable installation mechanism. Background Art
[0002] Earless retaining rings, also known as uniform cross-section retaining rings, are widely used in the field of mechanical assembly due to their unique earless design and uniform cross-sectional characteristics. This type of retaining ring does not have the protruding ears of traditional stamped retaining rings, so it has the advantages of compact structure and low installation space requirements.
[0003] The traditional installation method of earless retaining rings usually involves the following steps: first, workers need to pick up the retaining rings one by one; then, due to the earless design of the retaining rings, workers need to use fingernails or other tools to separate the ends of the retaining rings for subsequent installation; then, align the separated retaining ring openings with the grooves of the pin shaft for loading; finally, wrap the retaining rings around the grooves until the installation is complete.
[0004] However, picking up the retaining rings one by one is not only inefficient, but also increases the labor intensity of the workers. Secondly, for retaining rings with small diameters, using fingernails or other tools to separate the ends of the retaining rings is not only difficult, but also easy to cause damage to the workers' fingers, increasing safety hazards. In addition, the process of winding the retaining rings into the grooves one by one is also cumbersome and time-consuming, especially for double-layer earless retaining rings, which require several turns to complete the installation, further reducing work efficiency.
[0005] In actual mechanical assembly work, a product often needs to be installed with dozens of pins, and each pin needs to be installed with two retaining rings. Therefore, the number of retaining rings to be installed is huge. If the above manual method is continued to be used for installation, it will not only affect the assembly efficiency of the whole machine, but also increase production costs and the labor intensity of workers. Summary of the invention
[0006] 1. Technical problems solved In view of the deficiencies in the prior art, the present invention provides a portable installation mechanism for a shaft-use earless retaining ring, which solves the problems raised in the background technology.
[0007] 2. Technical solution To achieve the above objectives, the present invention is implemented through the following technical solutions: A portable mounting mechanism for a shaft with an earless retaining ring, comprising a main body and a cover plate sleeved on the top of the main body, a pressure rod is inserted into the bottom of the main body for sliding up and down, a magnetic seat is fixedly connected to the top of the pressure rod, and a positioning rod is inserted into the pressure rod for sliding up and down; The top end of the positioning rod and the top end of the cover plate are in the same horizontal plane, and the top end of the positioning rod has a diameter greater than the middle end and the bottom end of the positioning rod; A locking assembly is provided on the outer surface of the bottom end of the main body, and the locking assembly includes a locking shell, a locking release spring, a locking pre-compression spring, a pre-compression shell and a locking rod; A push ring is provided on the outer surface of the top end of the positioning rod, a push rod is fixedly connected to one side of the push ring, and the push rod is horizontally slidably connected to one side of the cover plate.

Through the design of the positioning rod and push ring, the rapid expansion and clamping of the retaining ring are achieved, simplifying the installation steps, improving work efficiency, and eliminating the need to manually separate the ends of the retaining rings.
[0009] Furthermore, a pop-up return spring is fixedly connected between the push rod and the cover plate; Through the above technical solution, by setting the pop-up reset spring, it is possible to achieve the effect that the push ring can automatically reset when the push rod is not pressed.
[0010] Furthermore, a main reset spring is fixedly connected between the inner top wall of the main body and the magnetic seat; Through the above technical solution and the provision of the main reset spring, the purpose of automatic reset of the magnetic seat can be achieved.
[0011] Furthermore, a pop-up spring is fixedly connected between the bottom of the positioning rod and the inner bottom wall of the pressing rod; Through the above technical solution and the provision of a pop-up spring, when the locking assembly releases the limit on the positioning rod, the positioning rod can automatically pop up and the retaining ring engaged with the positioning rod is located above the push ring.
[0012] Further, the locking shell is fixedly inlaid with the bottom end of the main body, the pre-stressing shell is slidably plugged with the locking shell, the locking rod is slidably connected with the pre-stressing shell, the two ends of the locking pre-stressing spring are respectively fixedly connected with the pre-stressing shell and the locking rod, and the locking release spring is respectively fixedly connected with the pre-stressing shell and the locking shell; Through the above technical solution, through the setting of the locking assembly, when the locking assembly is locked, the locking rod is inserted into the bottom end of the positioning rod, which can prevent the positioning rod from moving up and down along the main body. When the locking rod is unlocked, the locking rod is disengaged from the positioning rod, allowing the positioning rod to move up and down.
[0013] Furthermore, a switching handle is hingedly connected to the outer surface of the main body, the switching handle is crescent-shaped, both ends of the switching handle are rounded, and the two ends of the switching handle are respectively in contact with the push rod and one end of the preload housing; Through the above technical solution, by switching the setting of the handle, it is convenient for the user to squeeze the push rod or the pre-pressing shell.
[0014] Furthermore, the push ring is in an ∞ shape, and the inner hole diameter on the right side of the push ring is larger than the inner hole diameter on the left side of the push ring; Through the above technical scheme and the above settings, when the bottom end of the switching handle flips outward to release the positioning rod, the top end of the switching handle flips inward to squeeze the push rod, and then the larger inner hole of the push ring is sleeved with the top end of the positioning rod, so that the positioning rod drives the retaining ring to be located above the push ring, and then the push rod is reset, and then the smaller inner hole of the push ring is sleeved with the positioning rod, thereby facilitating the subsequent connection of the retaining ring with the external pin shaft.
[0015] Furthermore, a slide groove is provided on the outer surface of the pressure rod, and the locking rod is connected to the slide groove in an up-and-down sliding manner; Through the above technical solution and the setting of the slide groove, interference when the pressure rod is pushed can be effectively avoided when the positioning rod is locked.

DETAILED DESCRIPTION
[0023] The following will be combined with the drawings in the specific embodiments of the present invention to clearly and completely describe the technical solutions in the specific embodiments of the present invention. Obviously, the specific embodiments described are only part of the specific embodiments of the present invention, not all of the specific embodiments. Based on the specific embodiments of the present invention, all other specific embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0024] like Figure 1-5 As shown, a specific embodiment of the present invention provides a portable installation mechanism for a shaft with an earless retaining ring, comprising a main body 1 and a cover plate 2 sleeved on the top of the main body 1, a pressure rod 3 is inserted and slidably connected to the inner bottom end of the main body 1, a magnetic seat 4 is fixedly connected to the top of the pressure rod 3, and a positioning rod 5 is inserted and slidably connected to the inside of the pressure rod 3. Through the setting of the magnetic seat 4, when the pressure rod 3 is reset, the retaining ring sleeved on the surface of the positioning rod 5 can be driven to reset to the bottom end of the pressure rod 3. A main reset spring 10 is fixedly connected between the inner top wall of the main body 1 and the magnetic seat 4. Through the setting of the main reset spring 10, the automatic reset of the magnetic seat 4 can be achieved.
[0025] like Figure 1-5As shown, the top end of the positioning rod 5 and the top end of the cover plate 2 are in the same horizontal plane, and the top end diameter of the positioning rod 5 is larger than the middle end and the bottom end of the positioning rod 5. By increasing the top end diameter of the positioning rod 5, the retaining ring sleeved on the surface of the positioning rod 5 can be driven to move upward when the pressure rod 3 is pushed, and the retaining ring is expanded in the process, so that the uppermost retaining ring can be clamped on the top end of the positioning rod 5 due to interference fit, thereby achieving the feeding effect. A pop-up spring 11 is fixedly connected between the bottom of the positioning rod 5 and the inner bottom wall of the pressure rod 3. Through the setting of the pop-up spring 11, when the locking assembly 6 releases the limit on the positioning rod 5, the positioning rod 5 can automatically pop up and then make the retaining ring clamped by the positioning rod 5 be located above the push ring 7.
[0026] like Figure 1-5 As shown, a locking assembly 6 is provided on the outer surface of the bottom end of the main body 1, and the locking assembly 6 includes a locking shell 601, a locking release spring 602, a locking pre-stressing spring 603, a pre-stressing shell 604 and a locking rod 605. The locking shell 601 is fixedly inlaid with the bottom end of the main body 1, the pre-stressing shell 604 is slidably plugged with the locking shell 601, the locking rod 605 is slidably connected with the pre-stressing shell 604, the two ends of the locking pre-stressing spring 603 are respectively fixedly connected with the pre-stressing shell 604 and the locking rod 605, the locking release spring 602 is respectively fixedly connected with the pre-stressing shell 604 and the locking shell 601. Through the setting of the locking assembly 6, when the locking assembly 6 is locked, the locking rod 605 is inserted into the bottom end of the positioning rod 5, which can prevent the positioning rod 5 from moving up and down along the main body 1. When the locking rod 605 is unlocked, the locking rod 605 is disengaged from the positioning rod 5, so that the positioning rod 5 can move up and down.
[0027] like Figure 1-5 As shown, a slide groove 13 is provided on the outer surface of the pressure rod 3, and the locking rod 605 is slidably connected to the slide groove 13 up and down. Through the setting of the slide groove 13, interference can be effectively avoided when the pressure rod 3 is pushed when the positioning rod 5 is locked. A push ring 7 is provided on the top outer surface of the positioning rod 5, and a push rod 8 is fixedly connected to one side of the push ring 7. The push rod 8 is horizontally slidably connected to one side of the cover plate 2. When the push rod 8 is pressed, the push ring 7 can be driven to move. A pop-up reset spring 9 is fixedly connected between the push rod 8 and the cover plate 2. Through the setting of the pop-up reset spring 9, the effect of the push ring 7 being able to automatically reset when the push rod 8 is not pressed can be achieved.
[0028] like Figure 1-5As shown, the outer surface of the main body 1 is hinged with a switching handle 12, and the switching handle 12 is crescent-shaped. Both ends of the switching handle 12 are rounded, and the two ends of the switching handle 12 are respectively in contact with the push rod 8 and one end of the preload shell 604. Through the setting of the switching handle 12, it is convenient for the user to squeeze the push rod 8 or the preload shell 604, and the push ring 7 is in an ∞ shape, and the inner hole diameter on the right side of the push ring 7 is larger than the inner hole diameter on the left side of the push ring 7. Through the above setting, when the bottom end of the switching handle 12 is flipped outward to release the positioning rod 5, the top end of the switching handle 12 is flipped inward to squeeze the push rod 8, and then the larger inner hole of the push ring 7 is sleeved with the top end of the positioning rod 5, so that the positioning rod 5 drives the retaining ring to be located above the push ring 7, and then the push rod 8 is reset, and then the smaller inner hole of the push ring 7 is sleeved with the positioning rod 5, so as to facilitate the subsequent connection of the retaining ring with the external pin shaft.
[0029] It should be noted that before loading the retaining ring, please ensure that the surface of the positioning rod 5 is clean and free of oil and dirt to prevent the retaining ring from being obstructed during the sliding process. When installing the retaining ring to the pin shaft, please ensure that the surface of the pin shaft is clean and free of impurities to prevent affecting the tightness and installation effect of the retaining ring. After use, please clean up the residue inside the main body 1 in time to prevent affecting the next use. When pressing the pressure rod 3, please maintain moderate force to avoid excessive force that may cause damage to the equipment or deformation of the retaining ring. When the locking rod 605 locks and releases the positioning rod 5, please pay attention to observe the locking state to ensure that the positioning rod 5 is firmly installed or released smoothly. When using the switching handle 12, please ensure that the contact point between the switching handle 12 and the push rod 8 or the pre-load housing 604 is accurate to prevent operation failure due to misalignment. After installing the retaining ring to the pin shaft, please perform necessary inspections to ensure that the retaining ring is tightly inserted into the pin shaft groove to prevent loosening or falling off during use.
[0030] Working principle: First, the retaining ring is loaded. The user installs the retaining ring into the positioning rod 5 in sequence. This process is simple and quick. Then, by pressing the switching handle 12, the push rod 8 pushes the push ring 7 to move, and the larger push ring 7 inner hole diameter is on the same axis as the main body 1, so that the positioning rod 5 can be smoothly installed in the main body 1. When the positioning rod 5 is pressed to the bottom, the locking rod 605 will automatically lock to ensure that the positioning rod 5 is firmly installed in the main body 1. At this point, the loading process of the retaining ring is completed.
[0031] Next is the loading process of the retaining ring. The user uses the pin to press against the top groove of the positioning rod 5 and presses the pressure rod 3 at the same time. The magnetic seat 4 drives the positioning rod 5 and the retaining ring on the surface to rise together. When the pressure rod 3 is pressed to the bottom, the earless retaining ring to be installed is inserted into the top of the positioning rod 5. Then, the pressure rod 3 is released, and the pressure rod 3 returns to its original position under the action of the main reset spring 10. At the same time, under the suction force of the magnetic seat 4, the remaining retaining ring that is not inserted into the groove will also return to the bottom of the main body 1, ready for the next loading.
[0032] The last step is to install the retaining ring to the pin shaft. The user presses the switching handle 12 to make the locking rod 605 release the positioning rod 5, so that the retaining ring in the position is released upward to the push ring 7 together with the positioning rod 5. After releasing the switching handle 12, the push rod 8 is reset under the action of the pop-up reset spring 9, and the retaining ring is clamped on the push ring 7. At this time, the user inserts the groove at the top of the positioning rod 5 into one end of the external pin shaft, and presses the main body 1 to the bottom along the axial direction of the positioning rod 5. Under the forward push of the push ring 7, the retaining ring successfully completes the installation of the pin shaft. At the same time, the positioning rod 5 is locked again by the locking rod 605, ready for the next installation of the retaining ring.
[0033] Although specific embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the specific embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
